Earth attack is really the only effective way, if your opponent has any kind of Astral mages to preclude mindhunt.

Looming hell allows body guards to attack mages - works ok.. only in situations when you have assassins in the square (to make him use bodyguards) or perhaps when you have autosummoning troops.

Leprosy works... ok. So do Disease demons.

Whirlwind and Monkey attack don't work except IF the mage is in a coastal hex and IF the water is between you and him - you can pick him up and drop him in the water.
Which may or may not kill him.
